Can the Delphi TTaskDialog be made to use VCLStyles?

Solution

AFAIK, and as stated by TLama in his comment, this `TTaskDialog` just maps Windows API directly, you won't be able to do VCL Style directly.

BUT you may be able to do this, by using a hack similar to the one described in this article about using VCL Styles within a TWebBrowser.

This would be some work, or even not feasible, I suspect. You would have to hack all components created by Windows, which is not easy. The Task Dialog API does not provide a full and detailed COM interface, with a lot of callbacks, ready to be overriden, just like `TWebBrowser` does.

If you use our Open-Source Task Dialog emulation code as a start, you can enforce to use our emulation layer with pure VCL components. In this case, it will be easy to work with styles. Do not forget to send feedback and a patch to us, in order to let the unit be improved! Other users would like to benefit for such a nice features, I think. This is what is great with Open Source: you start something, publish, then contributions are integrated, and the result gets better. :)
